Working well for my Walstad-style aquariums, seems safe for fish
I have two planted aquariums I set up almost a year ago. I've been using less than the recommended dose of this fertilizer. I have cherry shrimp, pygmy corys, snails (mystery, Japanese trapdoor, ramshorn, bladder) and a betta fish, and none of them have shown distress from the fertilizer, even though the betta will get right under the dropper while I'm adding it to his tank. I wasn't using it in his tank for a while, but the valisneria started to die, and when I started fertilizing again (weakly weekly) it quickly started looking green and healthy. Other plants I have that are doing well include: anubius, bucephalandra, various cryptocorynes, salvinia, ludwigia, water wysteria, rotala, pearlweed, hairgrass, java moss. Also, this bottle is LARGE, and is going to take me years to get through.

A picture says a thousand words...
I was using another product that was twice the price and it ran out and I switched to my Leaf Zone as a backup at the time. I am noticing just as good or even better growth using Leaf Zone for several months now for half the price. I have mainly S. Repens and Dwarf Sag. Different plants, different needs, different outcomes. I inject CO2 so don't let the pictures fool you, but I had cut way back on dosing some time back, and my plants almost died. I did it to see just how important ferts were and it almost cost me my whole setup. I dose every time I can closer to when my light turns on for maximum uptake. Sometimes I dose several days in row, sometimes I go 3 to 4 days without it. I noticed my algae levels go down as well btw, maybe because it's not as strong. For the price, it is hard to beat as long as it fits your needs.

Plants, Fish, and Worms... Oh My!
I am impressed so far! Before and after pictures attached: same plants in/on the substrate but with a new layout and light. I also added some beautiful floating plants! FISH DON'T MIND, BUT WORMS DIED: I have dosed twice in the last 10 days. Both times right after a water change, administering only a half dose (I saw others mentioning their fish reacting badly and wanted to air on the side of caution). My fish don't seem to mind it, however it may have killed my black worms, not sure if it was the Leafzone but they all seem pretty dead for no other apparent reason. It's ok though, they're cheap and I have more. I keep 1 dwarf puffer, 1 serape tetra, many snails of all sizes, and a small black worm colony in my 5 gallon. Update: A full size dose has no adverse effects on my fish! Plants are doing AMAZING! Also seems my worms may have been shocked at first by the Leafzone and I lost several but I have not noticed new losses over time with continual use. I thing they just had to get used to it. PLANTS SEEM TO LIKE IT: The plants seem to be doing well. The bright green one in the middle of the picture, wisteria I think, had not been doing well, browning a lot on the edges of old leaves, so I got Leafzone. I started using it immediately and the wisteria shot out new growth that matched the height of the rest of the plant after a just a week and the browning on the old growth has slowed drastically and even stopped completely in some leaves! A runner broke off of my tall skinny plant (name? Lol); I replanted it and it got longer. I'll let you know if it sprouts. Most of the cobomba in my tank had previously died out, but I still have two small sprouts. One seems to be doing ok the other had some yellowing that appears to be rebounding with the Leafzone being used. I will report back on how it does on my cobomba sprouts. I AM LOW TECH: My aquarium is low light (standard light, nothing fancy), basic black gravel, wonder shells for an extra mineral boost, semi-hard water at 8.0ph, and no CO2 at appox 80 degrees. So this review is for API Leafzone for plants in a very low tech aquarium. I will keep you posted on my progress. Update: I got a new light($20) and some root tabs($7) to use alongside my Leafzone, my pants are so happy! New growth everywhere!

Great product!
When you use it like your supposed to if always gives your plants a boost. Ive used it here and there since I started keeping plants not as much as directed but I don't like a lot of extra nutrients in the water column so I use it less than recommended but never had any issues with plants growing just fine.
